AndEngine is a free open source OpenGL android game engine, developed by Nicolas Gramlich. It covers the most important OpenGL aspects, which means even if you don't have experience with OpenGL - you can still create great games/applications using this engine, the most important thing obviously is proper Java programming experience.

2. Benefits from using AndEngine:
Free and open source.
Most important aspects of every game are covered already by the engine.
You don't really need OpenGL experience (but it might be useful, obviously)
Fast, well designed and organized engine.
Relatively big, active and helpful community.
Great engine extensions.
Plenty of examples, showing off engine capabilities.
Lack of documentation is the main difficulty while starting (hard to understand every parameter etc)
But instead of documentation, this engine has great example projects, showing most every engine capability, it's a great way to check and understand how it work, hopeful while developing your own application. Also as mentioned, the engine community is very helpful, so you can always expect help from different developers. Hopefully this website will also help newcomers (as well as more experienced people) to understand how it works and improve the quality of your games!
